These days you've got to be looking in all directions in order not to beleft out in the technology scramble. Our department has just received asuggestion that we stop teaching with graphing calculators (TI-83's andTI-89's), which faculty outside our department have never understood orappreciated, and instead require all our students to buy a much moreuseful (as it was put) PDA. After all, it was pointed out to us, you canget software nowadays to emualte a scientific calculator on a palmtop,and you can even (sort of) run Microsoft Office in this environment.

Well, I've got a Palm M100 myself, and while I appreciate it for what itcan do, there is an awful big jump from making this device "do itsstuff" to the sort of creative exploration in the classroom and onhomework that a graphing or symbolic calculator allows. There is newsoftware (and hardware) appearing everyday, of course. I thought itmight be useful to ask if anyone on this list has so far experimentedwith, or even considered, using PDA's in a math classroom.
